mimosa
(Albizia julibrissin Durazz.)

Overview

Appearance

Albizia julibrissin is a small tree that is 10-50 ft. (3-15.2 m) in height, often having multiple trunks.

Foliage

It has delicate-looking, bi-pinnately compound leaves that resemble ferns.

Flowers

Flowering occurs in early summer, when very showy, fragrant, pink flowers develop in groups at the ends of the branches.

Fruit

Fruit are flat, 6 in. (15.2 cm) long seed pods that develop in the late summer.

Ecological Threat

Albizia julibrissin invades any type of disturbed habitat. It is commonly found in old fields, stream banks, and roadsides. Once established, mimosa is difficult to remove due to the long lived seeds and its ability to re-sprout vigorously. Albizia julibrissin is native to Asia and was first introduced into the U.S. in 1745. It has been widely used as an ornamental.
